Fritz Speakers

I would advise inquiring about a Xover upgrade I owned 2 pair ,and the drivers 

are excellent ,Xover is done good but so much better with top quality parts 

instead of $2 resistors, ask for Path audio ,they are $30 each but I believe only 2 resistors ,and for capacitors the VH audio Odam capacitors , check them out 

it will add maybe $6-700 more but worth every penny . 
This applies to most any brand  speaker under $15,000 they always skimp on the quality I have modded speakers mainly for friends and family for over 20 years your Sonic purity and details are improved for sure , ask about the option.

rule of thumb when a company will not show or describe the Xover or say proprietary it’s BS .you just want to know the brand name of the parts ,and all these parts would fit , go to VH audio and check and look up Path audio resistors , parts connecxion carry the resistors , and for speaker terminals don’t settle for cheap brass connectors , the WBT next gen speaker terminals are only $40 each , essential for best sonics they are gold  over Copper.

I have the Fritz Rev 7 SE and they sound excellent at low volume.  I usually listen at 40-70 db depending on the hour of the day.  They disappear regardless of volume and have outstanding soundstage and imaging as well.  They are a bit laid back, at least in my system, but I like that as I can listen without fatigue for hours.  I listen to a wide range of musical styles and genres and they work well with all of them.   I am running them with an MA8900 and Denafrips Pontus II.  Wonderful speakers, smooth and very well balanced.

I'm a newish owner/user of Fritz Carbon 7 SE mk2 speakers.

I purchased directly from John last summer.

My listening is usually in the mid 60's (db's) with peaks in the low 70's.  Sometimes when my wife is upstairs I'll listen very low and I'm astonished how, after allowing my hearing to acclimate to such a different presentation, how full and engaging the sound is.  It's like those speakers don't give up the low end or the top end when the volume goes low.  As long as I can keep my tinnitus in check, I can listen a long time at these late night low volumes and be totally in the music.

I couldn't be happier with that purchase.  I sometimes swap in my Magnepan LRS's but they typically get pulled for the Fritz's after a couple of days.

+1 @jaudio1  I also own the Carbon and 7 SEmk2s.  Also happen to own the LRS+ speakers. The Fritz do not require anything near the power (current) required by the LRS+. A 20wpc tube amp works well.

@mesch yes the Fritz don't require the power the LRS do...not anywhere close. 
Fortunately my Van Alstine amp plays very nicely with both sets of speakers. 

But ...the treat is, surprisingly I can also use my 3.5 watt 2a3 SET amp with the Fritz with great results.

I've been running these Fritz speakers without subs for a few weeks.   Honestly I don't miss the subs.  I have just enough room gain that everything is nice and full and balanced.   Am considering a digital crossover as some point to relieve the Fritz's (and amp) of a little low end duty and pass that on to stereo subs...but haven't embarked on that adventure yet.   But...there are plenty of happy listeners with Fritz speakers going without subs.
